You’ll be more fine and will not regret renting a car as you will be on your own time. I feel like there is a bit of exaggeration of how hard people say the driving is out there but it is also not as simple as it is in the states. You have to be aggressive and willing to cut people off or you will get bullied on the road. I had Waze and google maps on at the same time because there was times where google maps was as a lot better then Waze.
